9. The construction method of the assembled embedded energy-saving curtain wall system according to claim 1, characterized in that: in step 11, before the aluminum profile is fed, the number, color difference and specification model of the aluminum profile are checked to determine whether the aluminum profile conforms to the profile required by the actual workpiece, whether the oxide film on the surface of the aluminum profile is intact or not is not damaged, the aluminum profile with too deep nicks and large-area scratches is removed, the aluminum profile with distortion and bending deformation is corrected and then fed, and the glass processing quality is rechecked before the glass plate is assembled. The method is characterized in that the method is carried out on the aspects of appearance, size deviation and the like, unqualified products are not allowed to be used, and correspondingly recorded, classified and stored, the unqualified products cannot be mixed with qualified products to be placed, the splicing seams of the curtain wall and the splicing seams of the glass lattices are vertical and horizontal, the seam width is uniform and meets the requirement of a drawing, the variety, the specification and the color of the glass conform to the design, the color is basically uniform, the phenomena of alkali precipitation and mildew and obvious color difference do not exist, the glass with the phenomenon of film coating falling is forbidden to be used, the surface of the aluminum alloy decorative gland is smooth, the defects of deformation ripple or local crushing and smashing and the like which can be detected by naked eyes do not exist, the seam position must strictly meet the design requirement, and the shielding seal of hidden nodes is neat and attractive.
10. The construction method of the assembled embedded energy-saving curtain wall system according to claim 1, characterized in that: when the patterned glass plate is safely and protectively installed in the installation process, attention should be paid to the protection of the integrity of the aluminum alloy keel without load impact deformation, the frame type curtain wall glass plate is installed, and the installation is slowly carried out by using a glass sucker, so that the protection is paid attention to; the safety measures of the special construction mechanical equipment are that construction equipment (such as a special lifting car, a winch and the like) for installing the curtain wall must be carried out before use, strict inspection is carried out, trial run tests are carried out on various safety protection devices, an electric hand drill, an electric screwdriver, a welding gun, an electric tool and the like must be carried out for insulation tests, a manual glass sucker and an electric glass sucker must be used for testing the adsorption weight and the adsorption duration, workers using a handheld electric tool according to operation rules need to be matched with protective tools, the mechanical workers wear the protective tools according to the rules, and mechanical operators and bench workers cannot wear gloves when using the electric drill or the grinding wheel.
